The
Militia Act of 1903 established the present National Guard system, units raised by the states but paid for by the Federal Government, liable for immediate state service. If
federalized by Presidential order, they fall under the regular military chain of command. On 1 June 1920, the
Militia Bureau issued Circular No.1 on organization of National Guard air units. The Mississippi Air National Guard origins date to 18 August 1939 with the establishment of the 153d Observation Squadron and is oldest unit of the Mississippi Air National Guard. It is one of the
29 original National Guard Observation Squadrons of the
United States Army National Guard formed before
World War II. The 153d Observation Squadron was ordered into active service on 15 October 1940 as part of the buildup of the
Army Air Corps prior to the United States entry into World War II. On 24 May 1946, the
United States Army Air Forces, in response to dramatic postwar military budget cuts imposed by President
Harry S. Truman, allocated inactive unit designations to the
National Guard Bureau for the formation of an Air Force National Guard. These unit designations were allotted and transferred to various State National Guard bureaus to provide them unit designations to re-establish them as Air National Guard units. The modern Mississippi ANG received federal recognition on 12 September 1946 as the 153d Fighter Squadron at
Key Field, Meridian. It was equipped with F-47 Thunderbolts and its mission was the air defense of the state. 18 September 1947, however, is considered the Mississippi Air National Guard's official birth concurrent with the establishment of the United States Air Force as a separate branch of the United States military under the National Security Act. A second Mississippi ANG unit, the 183d Tactical Reconnaissance Squadron, was organized and federally recognized at Hawkins Field, Jackson and extended recognition as a new unit on 1 July 1953. On 15 October 1962 the 153d Tactical Reconnaissance Squadron was authorized to expand to a group level, and the 186th Tactical Reconnaissance Group was allotted by the National Guard Bureau, extended federal recognition and activated. On 1 July 1965 the 183d Air Transport Squadron was authorized to expand to a group level, and the 172d Air Transport Group was federally recognized at Jackson. Today, the 172d Airlift Wing (172d AW) flies weekly missions into harm's way to return wounded patients of the Total Force safely back to the U.S. The 186th Air Refueling Wing (186 ARW) provides worldwide air refueling support to major commands of the United States Air Force, as well as other U.S. military forces and the military forces of allied nations. After the
September 11th, 2001 terrorist attacks on the United States, elements of every Air National Guard unit in Mississippi has been activated in support of the global
war on terrorism. Flight crews, aircraft maintenance personnel, communications technicians, air controllers and air security personnel were engaged in
Operation Noble Eagle air defense overflights of major United States cities. Also, Mississippi ANG units have been deployed overseas as part of
Operation Enduring Freedom in Afghanistan and
Operation Iraqi Freedom in Iraq as well as other locations as directed. ==Notable members==
